As an unplanned preparation for these too events, I came across a couple of interesting sources last week:

Mobile Phones: The Next 4 Billion with Tomi Ahonen

An eye-opening presentation, where Tomi Ahonen highlights mobile differences and explains why the rate of adoption of mobile devices will be wider and faster than the rate of adoption of computers.

Tomi Ahonen has a very interesting argument about the screen size: if screen size would matter, a movie theater would be preferable to TV. I highly recommend listening to this presentation (and probably already twitted too much about it 😉 ).
